To di whom z't may concern:

Be it known that I, An'rnUn N. Doon, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a new and useful Dumping-Car, of which the following'is aspecification.

This invention has reference to improvements in dumpingr cars, and moreparticulurly tothe type of dump ears known as the V-body rocker dumpcar, which may be so constructed thatafter the body-ot the car is rockedto dump the load the empty body will automatically move back to therighted position, the body being movable to either side of the centerline of the car frame to dun/inthe load. Cars of this type are providedwitha V-shaped hopper supported at the ends by curved toothedinen'ibers, each of which may include practically a' halt circle, andthese semi-circular supporting' bodies travel on tracks arrangedtransversely of the length of the car, which tracks are perforated toreceive the teeth of the toothed members, so that the body or hopper ismoved toward one side or the other O the car frame, it has imparted toit u *rotative movement sutlicient to give the hopper -a quarter turn,which because of the shape of the hopper will cause a complete dischargeof the contents thereof. 1When the full dumping position has beenreached, stop'menibers inthe path of other stop members on the hopperprevent further movement of the latter, while the construction ot' thehopper is such that on the discharge ot the load the hopper will returnto its normal ri hted position.'

n practice there is a liability of the hopper or the body of the carbeing lifted or displaced from-its track, and `it is one ot the objectsof the present invention to provide means whereby the hopper or body isposi 'tively retained in operative relation to the track at all timesand under. all circumstances.

It is the further object of the invention to provide for thepositioningf of the hopper 'or body so that it may be readily loadedWithout the necessity ot elevating material to a height required forfilling; the car when the hopper or body is in the full rightedposition.

In order to realize these objects, the hopper is provided at each endwith a trunnion guide and thereis provided a guide bar c0- actingl withthe trunnion lo hold the rocker supports at the ends oi' the ar inpositive engagement with the rocker tracks. linrtherniore, there areprovided latches at each end of the car body enactingr with the truunionto lock the car body or hopper in the righted position, and, also, tohold the car body iu a partially dumped position in which the materialmay be readily filled into the hopper, thus facilitating the loading otthe car undericcrtain circumstance-i, but the latch mechanism does notinterfere with the dumping oi the hopper at either side-otI the tracl:when desired.

The invention will be best understood from a consideration of thefollowing detailed description, taken in connection 'with theaccompanviinr drawings formingr a part of this specification, with theunderstanding, however, that while the drawings show a practicalembodiment ot the invention, it may be otherwise embodied, so long asthe salient features of the invention are retained.

in the drawings:--i"igure i is au end elevation of a dump car embodyingthe present invention, the supportiin; rails beineshown in Cross sectionand the hopper in the rightedposition. Fig.. .5 u view similar to Fig'.1 with the hopper in the partly dumped position and showing in dottedlines the full dumped position. Fig. 3 is a side view of the rar withone end shown in elevation and the other in central longitudinalvertical section. Fig. 4 is a sei-lion ot' the car frame on the line L'l4 ot Fig. 3, the hopper being omitted. Fig. 5 is a perspective view ofoneA ot the latches.

Referring lo the dra wings, there is shown a car truck composed ot'V asubstantially rectangular 'trame l oi" structural steel; preferably ofchannel har, andthis frame 1 is supported by wheels 2 having their axles3 working in journal boxes 4 after the usual practice in dump Near eachend of the frame 1 there is mounted a cross beam 5 which may also be ofchannel steel, und in what may be termed the upper flange ot each beam 5is a longitudinal series of spaced perforations 6. Near each end of eachbeam 5 is an upright 7 suitably braced and united to the beam 5 andframe l by rivets and angle plates, as may be necessary. The uprights 7at the two ends ot nach beam E are in Haring relw tion one to the otheras they rise from the benin 5 anti tfhrir upper ends irc connected by aguido har 8 in parallel rotation to tho beam i and at, a suitabledistance above thifjv beam The. perforated i'langgcsi ot' the beams 5constituir tracks for onrrel angletrii's il serving as rorkcrs, cachharing a cul-roti flange niorahlc on thr trai-li' tlangn': ot tho boronA in rocking rt' tion thereto. flllach rocker ll has on it@ roi A .ige aserios oit tccth lllwhich may' hr 5r hij torni of projioct l ing Stullilahly spa and shapori to f gogo rr-rspt t; ro wrhio ationsa tl.
